A Numerical Study of 2 - D Turbulence
A simulation of 2-D turbulence in a square region with periodic boundary conditions has been performed using a highly accurate approximation of the inviscid Navier-Stokes equations to which a modified viscosity has reen added. A series of flow pictures show how a random initial vorticity distribution quickly a.ssumes a stringlike pattern which persists as the flow simplifies into a few "cyclone...
متن کاملA numerical method for computing unstable quasi-periodic solutions for the 2-D Poiseuille flow
where u u v are the components of the velocity, p is the pressure and Re is the Reynolds number defined in terms of the constant pressure gradient. As boundary conditions we suppose u x t v x t and u v p x L y t u v p x y t for L x IR y t The initial profile of velocities is simply subjected to the incompressibility condition, divu . We are concerned with the dynamics of Poiseuille flow in vary...
متن کاملNumerical study of bifurcations for the 2–D Poiseuille problem
We study the dynamics of two-dimensional Poiseuille flow. Firstly we check our calculations with previous results concerning the laminar solution and the minimum Reynolds number such that it becomes unstable. Next we studied time periodic solutions which, because of the imposed periodicity in the stream-wise direction, are rotating waves, what allow us to treat them as stationary flows in a mov...
متن کاملPeriodic Sorting on 2 - D Meshes 215
We consider the following periodic sorting procedure on two-dimensional meshes of processors: Initially, each node contains one number. We proceed in rounds each round consisting of sorting the columns of the grid, and, in the second phase, of sorting the rows according to the snake-like ordering. We exactly characterize the number of rounds necessary to sort on an l m-grid in the worst case, w...
متن کاملRectangular and Cylindrical TLDs with Rotatable Baffles to Improve Seismic Behavior of Structures, a Numerical Study
One of structural passive control methods is to use Tuned Liquid Damper (TLD). However, because of the nature of the TLD, only one tuning frequency can be created when the water is sloshing. To fix this problem, some installed rotatable baffles can be embedded inside TLD called Variably Baffled TLD (VBTLD) where by changing the angle of the baffles a tuning frequency range is created. This gives ...
